air supply is better with worms therefore more oxygen goes to the plants and makes them even higher

Traditionally, worms have been raised for fishing bait as well as a protein and enzyme source for various products, including animal food and biodegradable cleansers. Worms have also been used to manage agricultural wastes such as dairy manure. They convert waste into worm manure, a nutrient-rich, biologically beneficial soil product.
Vermicomposting is the use of worms as a composting method to produce vermicompost. Vermiculture is worm farming for the production of worms. In recent years, worm farming has been practiced on both a small and large scale with three complimentary goals in mind: waste diversion, vermicomposting, and vermiculture.
WASTE PROCESSING BY EARTHWORMS
Optimal conditions for earthworm activity
· Cool temperature: between 0 and 35oC
· Not too much water (85% moisture)
Mineralization in the earthworm gut
· As feed passes through the earthworm gut the material is mineralized and plant nutrients are available. The grinding effect of the gizzard and the passage through the gut leads to the formation of a granule (15) (16).
· Casts have a structure that is similar to a slow release granule: it has an organic matter core and a clay casing (1).
Casts benefit to plants
· Casts contain the necessary nutrients for plant growth: when added in sufficient amounts, as in 4-10 Kg casts / m2, casts can out-yield NPK fertilizers (100 Kg N / m2) (13).
· Casts increase plant dry weight and N, P, Mg and K uptake from the soil (12).
· The presence of earthworms increases plant growth and N uptake as opposed to unfertilized soil (19).
· Casts have a hormone-like effect that increases germination and growth rate (14).

It recycles nutrients into the soil by eating organic matter and then releasing the free nutrients to be used by the plant. Therefore, earthworms encourage plant growth. Other worms may harm plants...so I hope you mean earthworms or a worm that acts in the same way.

the worms mix the humus (black jelly-like substance on the top ov the litter) into the soil which acts like a fertiliser, and therefor improves the growth of the plants :)
hope this helped :)

well a worm as it makes a lot many holes therefore the air retaining capasity of the soil is increased. IT ACTS AS A WEED AS WELL AS PEST IN THE FIELD THUS DAMAGES THE PLANT. WORMS DO NOT CAUSE A LOT OF HARM TO THE SOIL ACTUALLY. IT ALSO ADDS MINERAL SALTS.

thier poop fertilizes it. also by respiration worms give off carbon dioxide which plants use in photosynthesis

all wastes that are coming from any digestive system produces nutients to the plants..
EARTHWORMS eat soil.
EARTHWOMS disposes soil with nutrients.
Therefore, it is helpful.
